Traffic growth at the airport is so big that Oslo Airport (OSL), Avinor and the Ministry soon will occupy space for a third runway. The construction of a new terminal is already in full swing.

It is not known when the construction of a third runway will start, but it is becoming more and more of an issue. It has earlier been stated that it won't happen until 2030, but with the trafficgrowt at OSL, it might come sooner. The case is now out for public consultation - and preliminary decision applies only to earmark land.

The airport wants a third runway especially during snowing condition. It wants to have 2 runways open at all times and have a third under continues snowplouging.

OSL wants a third runway to the east, but alot of people living there is needless to say not happy about it.

Building at OSL is already huge and will increase even more. The extension of the terminal in the same shape and style as the current terminal building will house new arrival and departure hall with 34 new check-in counters and new luggage handling facilities. Planned to be completed in 2017.

In the spring they will start to dig and build, 300-meter-long Pir North, which will shoot out from the current terminal in the northern direction and make room for 17 new aircraft parking, including 11 with "bridges".

There will be new shops and restaurant facilities and the airport train station is also undergoing a rewamp.

OSL has already reached it's max capacity of 23 million passengers. With the new builds that will be ready in 2017, it will have a capacity of 28 million passengers. OSL will possibly go passed CPH very soon as the airport in Scandinavia with the largest passenger number.

Looks like runway 3 makes the most sense, although why they could not have a runway on the west side in more or less the same place as 3 I don't know. (But from what you tell me it could appease the people living near the airport). Runway 2 looks like it would be very limited to departures to the north or landings to the south, otherwise you have to fly over the terminal and ramp on close final. It also seems too close to the existing runway. Runway 1 might be workable as well, but seems like it would have a long taxi much like in AMS...

Runway 3 also looks to have enough spacing for independent simultaneous IFR arrivals with the other eastern runway, a huge benefit when the west runway is closed, or if the airport ever reaches a traffic level where triple arrival streams are desired.

Quoting PITrules (Reply 3):Runway 3 also looks to have enough spacing for independent simultaneous IFR arrivals with the other eastern runway,

Just barely. 01R is 9,600 ft long, so going by that notion, the new runway 3 looks like it is anywhere from 3,500-4,000 feet from 01R.

Dont know how it works in Norway, but in the States, to do independant ILS approaches, the runways have to be at least 3,400 feet apart. Aslo, If the runways are between 3,400 and 4,300ft apart, you need a PRM (precision runway monitor) as well as a final monitor controller. Special pilot training is also required for ILS/PRM approaches.
Above 4,300 ft, a final monitor controller is enough.

As for dependant ILS approaches (staggered), the runways can be as close as 2,500ft apart.

us Air Traffic Controllers have a good record, we haven't left one up there yet !!

Not untill after 2020, but this is to secure the area, so no one build anything there

Much more challenging grounds, and more expensive

Think that's the whole point, and especially duing winter ops, this will be an advantage

You mean you guys actually plan your infrastructure in advance instead of improvising a patchwork solution once it is already too late? Wow, this is some revolutionary thinking going on up in Norway.

Hmmm... while certainly the most immediately available, lower-cost solution, it will cut through the two connecting taxiways, increasing taxi times. Imagine taxiing from a gate in the sout east side all around the terminal complex to depart from the West runway - BCN has a similar layout and it is not nice.

Quoting Mortyman (Thread starter):The airport wants a third runway especially during snowing condition. It wants to have 2 runways open at all times and have a third under continues snowplouging.

How bad is the snow issue for operations (I am not familiar)? OSL handled 230,000 movements last year. Similarly-laid out MUC handled 400,000, which is the typical capacity for such an airport layout, after that congestion starts. So on paper, runway capacity does not seem a limiting factor (yet) for OSL, but then again it does not have the same meterological conditions as MUC or others...

Quoting YYZatcboy (Reply 1):seems like it would have a long taxi much like in AMS...

Long taxi not only for planes, but for snow removal equipment. If operational performance under snowing conditions is the deciding factor, then having runways closer to the airport facilities and to each other will help in clearing them.

Europe is no different AFAIK. But 01R and "runway 3" would likely be operated with arrivals on one and departures on other, in which case they could be independent.

Usually we don't, so this might be an exception

One issue with OSL is the lack of high speed exits and other things that slows things down. But I also think they want to increase capacity during peaks

By having three separate runways, the snow must be really bad if they're not able to have two of them open at the same time

Quoting Mortyman (Thread starter):The airport wants a third runway especially during snowing condition. It wants to have 2 runways open at all times and have a third under continues snowplouging.

That makes a lot of sense.
The 3rd runway has helped HEL through some extreme winter conditions we have experienced in recent years, it has proved a really good investment. Now they have a slogan "HEL never freezes over"
